Photodynamic Therapy is a non conventional light therapy for treatment of cancer.
Photodynamic Therapy also known as PDT, uses photosensitive drugs (5-ALA, Foscan, Metvix, Tookad, WST09, WST11, Photofrin and Visudyne) which
are trigged by light from a specific wavelength usually red or infrared on the light spectrum chart. The drugs are administered
in different ways depending on the type of cancer being treated. When the light is applied to the drug it causes a singlet
oxygen molecule to form which attacks the tumor and destroys it from the inside out. Photodynamic Therapy is a proven
alternative treatment for many cancers. Clinical trials have taken place world wide and several hospitals do offer PDT as a
primary cancer treatment.
